Abstract

1,184,434. Modified epoxy resins. GEVAERT-AGFA N.V. 8 Aug., 1967 [30 Aug., 1966], No. 38552/66. Heading C3B. [Also in Division G2] Polyaddition polymers are made by adding 1 mole of a bis-epoxide to 1 mole of a secondary amine alkanol, and then allowing the mixture to react further to obtain higher molecular weight products, the reaction being stopped when the formation of gummy water-insoluble products begins. The reactants are (1) N- methyl-ethanolamine and 1 : 4-bis-(2 : 3-epoxypropoxy)-butane; (2) N-isopropyl-ethanolamine and 1 : 4-bis-(2 : 3-epoxypropoxy) - butane; (3) N-isopropyl-ethanolamine and N : N-bis-(2 : 3- epoxypropoxy)-isopropylamine; (4) N-isopropylethanolamine and 1 : 2-bis-(2 : 3 - epoxypropoxy)-ethane: (5) N-methyl-ethanolamine and N : N- bis-(2 : 3-epoxypropoxy)-isopropylamine ; and (6) diethanolamine and 1 : 4-bis-(2 : 3- epoxypropoxy)-butane. The products of (3), (4) and (5) are further reacted with maleic anhydride in dioxane and that of (4) is further reacted with succinic anhydride in tetrahydrothiophene-1 : 1 - dioxide. The bisulphite addition products of the reaction products of maleic anhydride and products (4) and (5) are also prepared.
